unRAID Wake On LAN/WAN Not working

[remotenerd]

I have installed Pulseway on my unraid server and it has ben working great. I can monitor everything and shutdown/restart the machine. However,  wake on lan is not working at all. I have enabled it in the BIOS and in the OS. I can wake the machine using my router, but not with the Pulseway app. In the config.xml file I have WoWAN set to true and the port to 9 (also tried 50000) and it still doesn't work. Is there something I am missing?

P.S. I also have a Windows machine that has WOW working perfectly.

Thank you for your help.
